Peculiarities of Transient Anelastic Relaxation in Fe-27%Ga Alloy with Different Metastable and Equilibrium Structures

Abstract:

In this paper, the effect of grain size of metastable D0₃ and D0₁₉ phases in rapidly cooled Fe-27at.%Ga alloy on their transition to equilibrium L1₂ phase at instant heating is studied using temperature dependent internal friction with additional support of neutron diffraction and SEM-EBSD methods. Using two alloys with a similar chemical composition, we demonstrated for the first time that a decrease in the grain size of metastable D0₃ phase, which was achieved by annealing at different temperatures followed by subsequent water quenching, leads to a faster transition to equilibrium state, i.e. that the D0₃ to L1₂ transition takes place at a lower temperature. The D0₁₉ to L1₂ transition takes place at a significantly higher temperature exhibiting better stability of overcooled D0₁₉ with respect to the D0₃ phase.
